UNLOADING-IVIACHINE.

To (ZZZ [07mm co'n'c'eMLg I 1' y Be it known that 1', PETE Mommy, of

the village of Enid, inthe Province of On tario Canada, haye invented certain ew and useful Improvements in Unloading Machines, of which the following is the speclficatlon. r

The invention relates to p p v I IIIJPIOVBIIIGI ltSlII unloading machines, particularly to a n a chine for unloadlng produce from a ra 1l Way car, and the principal object of the invention. is to prov idea self propelled machine for quickly and effectively withdrawing grain, coal or similar produce fjronra;

The shaftili the v various parts "or themachin e as shortly deg scribed.

h thi h ft I f l u edya bet l r 17 which is designed to driye a pinion18 located at the forward end of a rearwardly directed shaft 19 suitably carrled n bearo' an mounted on the platform and HON 11a. v

' v aw ing the rear end fitted with a friction puidies 29 and 30 suitably suspended from the frame 1 and fitted at their forward ends with further worms 31 and 32 which mesh with worm wheels 33 secured to the front axle 4.

According to the above arrangement it will be seen that by engaging one or other of the pulleys 21, 22 with the pulley 20 the machine can be advanced or backed on the tracks.

The sleeve is controlled by a spanning bell crank 34, connected by means of a connecting rod 35 with a conveniently located foot pedal 36 mounted on a forward lower table 37 suitably suspended from the forward end of the frame 1. The foot pedal is arranged within convenient range of the operators seat indicated at 38.

Directly above the table 37 I have provided a second table 39 whichis also suitably suspended from the frame 1, and the tables carry an upright center post e0 which extends through the top table and is permanently fastened to the bottom table by means of a flanged coupling 11.

42 is a forwardly extending swinging arm pivotally mounted on the lower end of the post 4&0 and beneath the table 37. This arm is fitted with a toothed segment 13 arranged concentric to the post and designed to mesh continuously with a worm H mounted on a short worm spindle f5 carried by suitable bearings l6 secured to the underside of the table.

The worm shaft is supplied with a beveled pinion 17 which meshes with a bevel gear is mounted on the forward end of a suitably carried driving spindle 49 which has the rear end thereof fitted with a beveled pulley 50 designed to engage with one or other of a pair of oppositely disposed coned pulleys 51 and 52 mounted on the shaft 11 and connected by a sleeve 53 feathered on the shaft as indicated'at 53. The position of the sleeve on the shaft is controlled by a spanning bell crank 54 controlled by a link 55 which passes forwardly to a controlling lever 56 mounted on the front platform and adjacent the operators seat.

From the above it is obvious that the attendant can turn the front arm in any 'direction by manipulating the hand lever, and that he can retain the arm any position by mowing the cone d pgilleys 51 and 52 sothat neitner engages with the pulley 50.

The arm 4-2 extends considerably in advance f itllehtbleilqanLh rtheefefi ard end thereof carried by a bracket which passes upwardly and backwardly to' the post in a location above the top table,.the rear end thereof being swung on the post.

58 is a roller operating on the upper surface of the table 37 andeonnected by means of a bracket 58 to the arm 42. This roller rides continuously on the table when the arm is turned. 7 I p The forward end of the arm and the upper portion of the bracket 57 provide bearings for a front driven shaft 59 which is formed from two sections, a stationary top section 59 and a rotatable lower section 59 the lower section being fastened to the top section by means of a coupling 60.

The lower end of the shaft, below the arm, is forked to provide side carrying arms 59 and 59, which carry a conveyer cross shaft 61 and on this shaft 1 mount a pair of chain wheels 62 and 62 and suspend the rear ends of a pair of side bars 63 and 63, the forward ends of which provide bearings for a second conveyer shaft 6-i which is fitted with a pair of chain wheels Get and 6& similar to those 62 and 62. These front and rear pairs of chain wheels are connected by chains 65 provided at intervals with cross slats 66 onv which I mount outstanding scraper plates 67. v

The above arrangement, when driven, provides an endless conveyer which I utilize for scraping out the produce from the car, as later explained.

The nose or forward end of the conveyer is suspended by means of a bail-bar 68 connected by means of an adjusting cable 69 with a winding drum 70 located on the top table and arranged such that it can be-rotated for adjusting purposes through the manipulation of a crank 71 disposed on the underside of the platform and within convenient range of the operator. The cable is carried by pulleys 72 and 72 located on the upper ends of the post 40 andthe shaft 59.

In order that the conveyer may be ,adjusted to accommodate the various heights of cars, I have made the shaft 59 so that it can be raised or lowered, this being accomplished by threading the upper end thereof and having a wheel 73 threaded on the 1 shaft and fastened to the bracket 57 in such a mannerthat the wheel will rotate and'effeet the raising or lowering of the shaft. The manner in which this latter fastening is made is shown in Fig. 7 of the drawings, where it will be noticed that the underside of the wheel is supplied with an extending flange '73 which is received beneath the fastening plate 73 secured to theflbrackeu This wheel .73 is connected so that it can be driven by the engine This is'accomplished by passing a cable 74 around the wheel backwardly through suitable guiding pulleys 75 carried by the upper end of the post, then laterally over further guid in pulleys 76 and 7 6 mounted on-the table and finally downwardly to a winding drum 77 mounted on a short shaft 7 8 carried by suitable hangersj78" suspended from the underside of the top table.

The shaft 7 8 is driven by means of a beveled pinion 79 which meshes continuously with a bevel wheel 79 located at the forward end of a suitably mounted driving spindle 7 9 having the rear endfitted with a coned pulley 79 designed to engage with one or other of a pair of coned pulleys 80 and 80 mounted on the shaft 11 andconnected by means of a sleeve 80* feathered on the shaft as indicated at 80 The sleeve is controlled by a spanning bell crank 81' connected by means of a link 81 with a suitably located lever 82 mounted on the lower table adjacent the'seat. I

The lower section 59 of the shaft 59 is arranged sothat it can be turned to swing the conveyer with respect to the arm. This is accomplished by means of a pulley 83 feathered on the shaft as shown at 83- but free to ride thereon when the said shaft is raisedor lowered. V r l The pulley 83 is driven by a continuous cable 84 having the ends extending back-, wardly through suitable guiding pulleys 85 mounted in the post lO and having their rear extremities connected to a 1 winding drum 86 carried by a short shaft 87 mounted-- in suitable standards 87" disposed on thebottom table. I

The short shaft 87 is fitted with a bevel pinion 88 which meshes continuously with a bevel wheel 89 located at the forward end of a suitably mounted driving spindle 89 havingthe rear end thereof supplied with a coned pulley 89 designed to engage with one or other ofa pair of oppositely disposed cone pulleys 90 and 90 mounted on the shaft 11 and connected by a sleeve 91 feathered on the said shaft as indicated at 91, This sleeve is controlledby a spanning bell crank 92 connected by a connecting rod 92 with a suitably disposed lever 92 mounted on the front platform adjacent the seat,

In orderthatthe conveyer'may be driven in all the positions that it may assume, I

have provided a square driving shaft 93 im- I mediately tothe rear of the shaft 59, which shaft is carried in special bearings'provided on the armand on the bracket 57; These bearings are best shown in Figs. 11 and 12 of the drawings, where itz'will be observedthat the square body of the shaft passes to the bracket or the arm, as the case may be. i

'- The'lower end ofthe shaft carries a drivinig'pin'ion 94 which is slidable on the shaft and is fitted with an extendingsleeve rotatably mounted in-the connecting bar 94 which passes forwardly and receives rotatably the sleeve 95' of a driving gear wheel "95 rotatably'mounted on the lowerlend of the lower section 59 of the shaft 59. This bar, when the shaft 59 is'adjusted vertically, causes the pinion 9-1 to raise'or lower on squareshaft with the gear wheel 95.

v To the gear wheel 95=I connect a bevel gear 96 also rotatably mounted on the lower section of the shaft 59 andldesigned to mesh continuouslywith a bevel pinion-96 carried bya short spindle 96 extending outwardly from the arm 59*.

' 'Tothe'pinion 96- I fasten a chain wheel 97 which drives through 'a'chain 97 a further ch'ain wheel 97 2 mounted on the ad-, jacentend of the conveyer shaft 61. I

The square shaft is drivenby means ofla' pulley 98 mounted on said shaft in a loca tion directly above the rearwardly extending the portionof the bracket 57. The pulley 98 is Y the rear end of which is supplied with a cone pulley a designed to engage a' beveled pulley d mounted on a sleeve fwhich is feathered on the shaft 11 as indicated at g. This sleeve is controlled by means of a spanning bell crank 5h? connected by means of a connecting rod i with a suitably j disposed lever 12 mounted on the lower tableadjacent the seat;

Thea'bove completes the description of the parts, but in order to better understand the machine I will "now describe'the manner in I The machine is brought up to the car,'on

the tracks, 'by'inanipulating the foot pedal 36 which controls the sleeve 23. ln'any po sition themachine'is brought'to a standstill it"rernains locked in that position, owing to the worm drive. The conveyer is then adjustedvertically to accommodate the height of the car which it is to unload, and this is done by manipulating the, lever 82 which controls the sleeve 80*. It is obvious that as the wheel 73 is rotated in one direction or the other, it will cause the shaft 59 to raise or lower owing to the fact that the said wheel is held against raising by means of the fastening plate. After the conveyer has been adjusted to the proper height the nose of it is swung into the interior of the car through the car door opening, this being accom-.

plished by operating the lever 92 which controls the sleeve-91. If it is necessary at this time to raise or drop the nose of the conveyer this can be done by manipulating the winding crank 71. The work of sweeping the grain out of the car is then started by throwing in the lever 42 which controls the sleeve f, to drive the conveyer. 'When the grain adjacent the door has been swept out by the plates of the conveyer, the grain farther away from the door can be handled bymoving up the car, if needs be, and adjusting the swinging arm P2 to admit it into the doorway, and readjusting the conveyer. The position of the arm is controlled by the lever 56 which is directly connected with the sleeve 53. A position such as outlined above, with the end of the arm in the car and the conveyer also within the car, is shown in Fig. 2 of the drawings. According to the arrangement provided, it is possible, by advancing or receding the car and adjusting both the arm and the conveyer, to make the conveyer reach allpoints in the car.

The grain caught by the plates of the conveyer is swept out through the doorway opening of the car and falls through the grids into the pit.

In cases Where the adjustment is made such that the conveyer is passing lengthwise of the car and adj acent one side thereof, 1 suggest that it would be advisable to insert a board angularly across the car and at the side of the doorway farthest from the rear end of the conveyer. The position of such a board is indicated in Fig. 2 of the drawings, at ;9. It will be seen that asthe grain is driven back by the conveyer it will be deflected sidewise by the board and out through the door.

Although I have shown special driving connections operated by the engine for working the various parts, still it will be understood that these can be modified in a diversity of ways while accomplishing the same objects, as any of the well known reversible driving connections would operate to equal effect. Such changes would be purely, mechanical and would not amount, in the broader sense, to invention.

While the device has been described for unloading grain, still it will be understood Leas es that it can be used for unloading coal or other similar produce.
